ssl - What TLS method is better for port 587? -

-

what suggested method securing submission port 587 on smtp server, starttls command or direct tls layer?

i tend use (mandatory) starttls command , not direct tls layer. in case of problems, starttls command can disabled without changing mua`s configuration. think in case of direct usage of tls layer not straightforward.

are there other suggestions, opinions ? didn't find out if standardised in rfc.

you don't have choice. port 587 starttls command. standard port allowing ssl-wrapped ("direct tls") connection port 465.
